摘　　要：以阿克苏市防护林为例,对典型绿洲农田防护林的健康状况进行诊断与评估。采用样线法和样带法进行样地布设,调查树种组成、生物量、年龄结构及退化成因等。结果表明:阿克苏市防护林体系相对健全,林网完整度较高,但仍存在一些问题,主要体现在年度防护林造林任务分配不均、空间分布上呈现出显著的不合理性、农田防护林在不同土壤立地条件下的生长状况差异显著以及树种选择较单一等方面。In this study,the health status of typical oasis farmland protective forests was diagnosed and evaluated by taking Aksu City protective forest as an example.The sample plots were laid out by using the sample line method and sample strip method to investigate the species composition,biomass,age structure and causes of degradation.The results of the study showed that the protective forest system in Aksu City was relatively sound and the integrity of the forest network was high,but there were still some problems,which were mainly reflected in the uneven distribution of annual protective forest afforestation tasks,the significant irrationality of the spatial distribution,the significant differences in the growth status of farmland protective forests under different soil conditions,and the single selection of tree species,and so on.
